PRODUCT FEATURES
OPERATION
This heater is clean burning. It requires no outside
venting. There is no heat loss out a vent or up a
chimney. Heat is generated by realistic, dancing
yellow flames. This heater is designed for vent-
free operation. State and local codes in some ar-
eas prohibit the use of vent-free heaters.
SAFETY PILOT
This heater has a pilot with an Oxygen Depletion
Sensing (ODS) safety shutoff system. The ODS/
pilot is a required feature for vent-free room heat-
ers. The ODS/pilot shuts off the heater if there is
not enough fresh air.
PIEZO IGNITION SYSTEM
This heater has a piezo ignitor. This system re-
quires no matches, batteries, or other sources to
light heater.
AIR FOR COMBUSTION
AND VENTILATION
WARNING: This heater shall
notbeinstalledinaconfinedspace
or unusually tight construction
unless provisions are provided
foradequatecombustionandven-
tilation air. Read the following in-
structions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
Today’s homes are built more energy efficient than
ever. New materials, increased insulation, and new
construction methods help reduce heat loss in
homes. Home owners weather strip and caulk
around windows and doors to keep the cold air out
and the warm air in. During heating months, home
owners want their homes as airtight as possible.
While it is good to make your home energy effi-
cient, your home needs to breathe. Fresh air must
enter your home.All fuel-burning appliances need
fresh air for proper combustion and ventilation.
Exhaust fans, fireplaces, clothes dryers, and fuel
burning appliances draw air from the house to
operate. You must provide adequate fresh air for
these appliances. This will insure proper venting
of vented fuel-burning appliances.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Section 5.3,Air
for Combustion and Ventilation.
All spaces in homes fall into one of the three fol-
lowing ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 5 through 7 will help
you classify your space and provide adequate ven-
tilation.

www.desatech.com 113084-01A
6
Unusually Tight Construction
The air that leaks around doors and windows may
provide enough fresh air for combustion and ven-
tilation. However, in buildings of unusually tight
construction,you must provide additional freshair.
Unusually tight construction is defined as
construction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous
water vapor retarder with a rating of
one perm (6 x 10-11 kg per pa-sec-m2)
or less with openings gasketed or
sealed and
b. weather stripping has been added on
openable windows and doors and
c. caulking or sealants are applied to ar-
eas such as joints around window and
door frames, between sole plates and
floors, between wall-ceiling joints, be-
tween wall panels, at penetrations for
plumbing, electrical, and gas lines, and
at other openings.
If your home meets all of these three crite-
ria, you must provide additional fresh air.
See Ventilation Air From Outdoors , page 7 .
If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow For Fireplace Location,
column 2.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/NFPA
54 defines a confined space as a space whose vol-
ume is less than 50 cubic feet per 1,000 Btu per
hour (4.8 m3per kw) of the aggregate input rating
of all appliances installed in that space and an un-
confined space as a space whose volume is not less
than 50 cubic feet per 1,000 Btu per hour (4.8 m3
per kw) of the aggregate input rating of all appli-
ances installed in that space. Rooms communicat-
ing directly with the space in which the appliances
are installed*, through openings not furnished with
doors,areconsideredapartoftheunconfinedspace.
*Adjoiningrooms are communicatingonly if there
are doorless passageways or ventilation grills be-
tween them.

DETERMINING FRESH-AIR FLOW
FOR HEATER LOCATION
Determining if You Have a Confined or
Unconfined Space
Use this work sheet to determine if you have a
confined or unconfined space.
Space: Includes the room in which you will install
fireplace plus any adjoining rooms with doorless pas-
sageways or ventilation grills between the rooms.
1. Determine the volume of the space (length x
width x height).
Length x Width x Height =__________cu. ft.
(volume of space)
Example: Space size 20 ft. (length) x 16 ft.
(width) x 8 ft. (ceiling height) = 2560 cu. ft. (vol-
ume of space)
If additional ventilation to adjoining room is sup-
plied with grills or openings, add the volume of
these rooms to the total volume of the space.
2. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
__________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example: 2560 cu. ft. (volume of space) x 20 =
51,200 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in
the space.
Vent-free fireplace __________ Btu/Hr
Gas water heater* __________ Btu/Hr
Gas furnace __________ Btu/Hr
Vented gas heater __________ Btu/Hr
Gas fireplace logs __________ Btu/Hr
Other gas appliances* + __________ Btu/Hr
Total = __________ Btu/Hr
* Do not include direct-vent gas appliances. Di-
rect-ventdrawscombustion air from the outdoors
and vents to the outdoors.
Example:
Gas water heater ______________ Btu/Hr
Vent-free fireplace ______________ Btu/Hr
Total ______________ Btu/Hr
4. Compare the maximum Btu/Hr the space can
support with the actual amount of Btu/Hr used.
________ Btu/Hr(maximumthespacecansupport)
________ Btu/Hr(actual amount of Btu/Hr used)
Example: 51,200 Btu/Hr (maximum the space
can support)
70,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the above example is a confined space
because the actual Btu/Hr used is more than the maxi-
mum Btu/Hr the space can support. You must pro-
vide additional fresh air.Your options are as follows:
40,000
+ 30,000
= 70,000

A. Rework worksheet, adding the spaceofanadjoin-
ing room. If the extra space provides an uncon-
finedspace, remove door toadjoiningroom or add
ventilation grills between rooms. See Ventilation
Air From Inside Building.
B. Vent room directly to the outdoors. See Ventila-
tion Air From Outdoors.
C. Install a lower Btu/Hr fireplace, if lower Btu/Hr
size makes room unconfined.
If the actual Btu/Hr used is less than the maximum
Btu/Hr the space can support, the space is an uncon-
fined space.You will need no additional fresh air ven-
tilation.
WARNING: If the area in
which the heater may be oper-
atedissmallerthanthatdefined
asan unconfinedspace orifthe
building is of unusually tight
construction, provide adequate
combustion and ventilation air
byoneofthemethodsdescribed
in the National Fuel Gas Code,
ANSI Z223.1/NFPA 54 Section
5.3 or applicable local codes .
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining un-
confined space. When ventilating to an adjoining
unconfined space, you must provide two perma-
nent openings: one within 12" of the ceiling and
one within 12" of the floor on the wall connecting
the two spaces (see options 1 and 2, Figure 2).
You canalso removedoor into adjoining room (see
option 3, Figure 2). Follow the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for
Combustion and Ventilation for required size of
ventilation grills or ducts.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills
or ducts. You must provide two permanent open-
ings: one within 12" of the ceiling and one within
12" of the floor. Connect these items directly to
the outdoors or spaces open to the outdoors. These
spaces include attics and crawl spaces. Follow the
National Fuel Gas Code, ANSI Z223.1/NFPA 54,
Section 5.3, Air for Combustion and Ventilation
for required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet
or outlet air into attic if attic has a thermostat-con-
trolled power vent. Heated air entering the attic
will activate the power vent.

The gas inlet connection for the stove heater is
located on the lower right-hand side of the stove
when viewed from the front of the unit. The gas
connection can be made either through the bot-
tom right side or through the lower back opening
asillustrated in Figure14. Make suregas log heater
is secured to the stove cavity assembly.
For propane/LP units, installer must supply an
external regulator. The external regulator will re-
duce incoming gas pressure. You must reduce in-
coming gas pressure to between 11 and 14 inches
of water. If you do not reduce incoming gas pres-
sure, heater regulator damage could occur. Install
external regulator with the vent pointing down as
shown in Figure 15. Pointing the vent down pro-
tects it from freezing rain or sleet.
CAUTION:Useonlynew,black
ironorsteelpipe.Internally-tinned
copper tubing may be used in
certain areas. Check your local
codes. Use pipe of 1/2" diameter
or greater to allow proper gas
volume to heater. If pipe is too
small, undue loss of volume will
occur.

Installation must include a equipment shutoff
valve, union, and plugged 1/8" NPT tap. Locate
NPT tap within reach for test gauge hook up. NPT
tap must be upstream from heater (see Figure 16
on page 13).
IMPORTANT: Install equipment shutoff valve in
an accessible location. The equipment shutoff
valve is for turning on or shutting off the gas to
the appliances.
Check your building codes for any special re-
quirements for locating equipment shutoff valve
to fireplaces.
Apply pipe joint sealant lightly to male threads.
This will prevent excess sealant from going into
pipe.Excess sealant in pipe could result in clogged
heater valves.
WARNING: Use pipe joint
sealantthatisresistanttoliquid
petroleum (LP) gas.
We recommend that you install a sediment trap in
supply line as shown in Figure 16, page 13. Lo-
cate sediment trap where it is within reach for
cleaning. Install in piping system between fuel
supply and heater. Locate sediment trap where
trapped matter is not likely to freeze. A sediment
trap traps moisture and contaminants. This keeps
them from going into heater controls. If sediment
trap is not installed or is installed wrong, heater
may not run properly.

INSPECTING BURNERS
Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 25 showsa correct pilotflame pattern. Figure
26 shows anincorrect pilot flamepattern. Theincor-
rectpilotflame is not heating the thermocouple.This
will cause the thermocouple to cool. When the
thermocouple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown in Fig-
ure 26
• turn heater off (see To Turn Off Gas to Appli-
ance, page 15
• see Troubleshooting, pages 19 through 21
Note: The pilot flame on natural gas units will
have a slight curve, but flame should be blue and
have no yellow or orange color.
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in
the fitting at the burner entrance. These holes may
become blocked with dust or lint. Periodically in-
spect these holes for any blockage and clean if
needed. Blocked air holes will create soot.
MAIN BURNER
Periodically inspect all burner flame holes with
the heater running.All slotted burner flame holes
should be open with yellow flame present. All
round burner flame holes should be open with a
smallblue flame present. Some burner flame holes
may become blocked by debris or rust, with no
flame present. If so, turn off heater and let cool.
Remove blockage. Blocked burner flame holes
will create soot.

CLEANING AND
MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep
control areas, burner, and cir-
culating air passageways of
heater clean. Inspect these ar-
eas of heater before each use.
Haveheaterinspectedyearlyby
a qualified service person.
Heater may need more frequent
cleaning due to excessive lint
from carpeting, pet hair, bed-
ding material, etc.
WARNING: Failure to keep
theprimaryairopening(s)ofthe
burner(s) clean may result in
sooting and property damage.
BURNER INJECTOR HOLDER AND
PILOT AIR INLET HOLE
Theprimary air inlet holesallow the properamount
of air to mix with the gas. This provides a clean
burning flame. Keep these holes clear of dust, dirt,
lint, and pet hair. Clean these air inlet holes prior to
each heating season. Blocked air holes will create
soot. We recommend that you clean the unit every
three months during operation and have heater in-
spected yearly by a qualified service person.
We also recommend that you keep the burner tube
and pilot assembly clean and free of dust and dirt.
To clean these parts we recommend using com-
pressed air no greater than 30 PSI.Your local com-
puter store, hardware store, or home center may
carrycompressedairinacan.You can use avacuum
cleaner in the blow position. If using compressed
air in a can, please follow the directions on the can.
Ifyou don't followdirections on the can, you could
damagethepilotassembly. Note: Removing the rear
panel (Figure 5, page 8) and top grate(s) of your
stove will make cleaning easier.
1. Shut off the unit, including the pilot. Allow
the unit to cool for at least thirty minutes.
2. Inspect burner, pilot, and primary air inlet
holes on injector holder for dust and dirt (see
Figure 27).
3. Blow air through the ports/slots and holes in
the burner.
4. Check the injector holder located at the end
of the burner tube again. Remove any large
particles of dust, dirt, lint, or pet hair with a
soft cloth or vacuum cleaner nozzle.
5. Blow air into the primary air holes on the in-
jector holder.
6. In case anylargeclumps of dusthavenow been
pushed into the burner repeat steps 3 and 4.
Clean the pilot assembly also.Ayellow tip on the
pilot flame indicates dust and dirt in the pilot as-
sembly. There is a small pilot air inlet hole about
two inches from where the pilot flame comes out
of the pilot assembly (see Figure 28). With the
unit off, lightly blow air through the air inlet hole.
You may blow through a drinking straw if com-
pressed air is not available.
